I see socapex runs for speakers on touring Broadway shows all the time.

We use Socapex fairly often for our monitor rig when running biamped wedges. 1 trunk breaks to 4x nl4. We have socapex> NL8 as our B rig fly looms too.

All the audio connectors are painted blue, all the lighting is painted red, we make sure to mention that to stagehands if both are being used.

It is pretty standard.

You just need to be aware of what cables are going where. 

With any cable you should not be "randomly" plugging it in.  Know what it is and where it goes.
I see it all the time too.  In a perfect world it's fine.  In a tour situation it's probably not as big of problem.  In this case it was a corporate show with different departments not communicating all that well.

In the OP's case he is starting out with a new cable system.  I was trying to dissuade the use of an AC connector for speakers.

Why not just use NL8.  That would give you what you need.  I assume you are running the tops passive (not biamped) so you would get a separate feed to each box with the right conductors and it us a lot less weight than Soco.  You can make a short squid that is NL8 to four NL4s and use a coupler to connect them so that you won't lose the versatility of the NL8 cable.

+1

However, I would use NL8 to whichever of these Whirlwind SBNL boxes you need. In my small rig I use NL8's to to both sides for bi-amped tops and subs and another NL8 that carries 4 passive wedge mixes. It's a very versitile system. I think Socapex might be overkill for you. And, the Socapex connectors/cable will cost more if you don't already own it.

I agree with this approach. I use NL8 for tri-amped tops and also NL8 for 4 passive wedge mixes the daisy chaining works like a charm and saves a bunch of cable runs. Using socapex for this small a set up seems like waaaay overkill. There are easier (and lighter) ways to accomplish the same thing.

originally i was going to use NL8 but i stumbled upon a pre made 19 pin socapex with nl4 fanout and break out box already pre made. This later will allow me to bi amp and add speakers for future flexibility. I also have 0 NL cables right now and literally just bought these speakers. I used to only have a 1/4" system.

So this is a completely new system to me. The cable is already made correctly I metered it all just need to buy a custom rack panel now. Does anyone suggestions on custom panels?

This cable actually was previously used by DB sound. Also my system is used for one offs that i do on my own. No other lighting companies or audio companies are involved so the confusing the cable thing will never be an issue.


For touring this is a very normal thing but companies have different cables that they use to do it. I say this just from working for a touring company as of recently.

These pre made ones are pretty nice and not wired for lighting.

From the picture, that cable looks to be 4 x NL4 to a Socapex Female connector. This would normally be a break in cable rather than a break out.

A socapex panel for an amp rack would normally have a female connector on it and the break out cable for the speaker end would be a male socapex to 4 x NL4. This means you don't have exposed pins with speaker voltage on anywhere in the system.

Don't use SOCA for speakers!  I just now got home from a gig where a helpful stage hand or audio guy connected to a random "extra" SOCA on the truss.  Fortunately we caught it before powering up the 208V moving light distro and 120V dimmers.  We were very close to frying some speakers.

2 things:

1) Soca is the industry standard for a good reason. It works and its ubiquitous. Good labelling and competent crew fixes these problems. Lots of companies over here (EU) actually use non-shorted ground soca for lighting so that it is interchangeable.

2) I've seen a hang of D&B Q1 be connected to a 240v lighting soca and livened up. It made a nasty noise, but it worked fine, no damage.

Years ago I worked on a "Soca-Rig", and the connectors were reversed (as compared to the lighting rig). You couldn't patch audio to lights even if you wanted to...
Our inventory didn't have the shorting rings, so the same cables could be used for the whole set-up.
In the "old days", soca was real time saver when you were screwing with 20-30 boxes a side. Soca to EP-6 was the "standard" breakout, with soca patch panels at the amps.

I would not hesitate to use it today, if I had the need.
